In the manual small press for processing empty cans according to the first aspect of the present invention, the movable lever is separated from the receiving plate, and the operating lever is operated while the empty can is set between the receiving plate and the movable plate. At the operation start position rotated in the direction opposite to the receiving plate, engage the engaging tooth of the engaging tooth member with the engaging tooth of the rack member, and then manually operate the operating lever toward the receiving plate (that is,
When it is rotated by an arbitrary angle in the pressing direction), the engaging teeth of the engaging tooth member are locked by the locking teeth of the rack-shaped member, so that the shaft member and the movable plate move toward the receiving plate side (that is, the movable plate). , Press direction). By moving the movable plate by a predetermined distance, the empty can is crushed by a predetermined distance between the movable plate and the receiving plate. Next, the operation lever is rotated in the counter-press direction by an arbitrary angle, and then the engagement teeth of the engagement tooth member are re-engaged with the engagement teeth of the rack-shaped member. When the above operation is repeated a plurality of times, the empty can is gradually and strongly crushed.

After the crushing process of the empty can is completed, the engagement between the engaging tooth of the engaging tooth member and the engaging tooth of the rack-shaped member is released, and the shaft member and the movable plate are connected via the operating lever. Remove the crushed empty can to the outside by separating it from the receiving plate.

If the lever length of the operating lever is L and the length from the center of the shaft member to the tip of the engaging claw member is d, the manual operating force input to the operating lever is approximately L / d. Since the empty cans can be crushed and processed with the power boosted by the power factor of 1, the empty cans can be pressed strongly with a small manual force, and depending on the design, empty cans with high strength such as steel cans can also be processed. Can be configured as a small press. Further, since the movable plate and the receiving plate are arranged to face each other and the manual driving force from the operation lever is strongly boosted to press the empty can, the overall structure is small, lightweight and simple. It can be a press.

In the compact press according to the second aspect, a pair of operation levers are provided on both sides of the movable plate, and driving force input side end portions of the pair of operation levers are integrally connected by a connecting lever member. Since the pair of engaging tooth members corresponding to the pair of operation levers and the pair of rack-shaped members are provided, both ends of the movable plate can be uniformly pressed and driven, so that the empty can can be stably pressed. In addition, since the small press can be transported via the connecting lever member and the pair of operation levers, the handleability is excellent.

According to another aspect of the compact press of the present invention, the facing surface of the rack-shaped member is formed parallel to the rotating surface of the operating lever, and the engaging tooth member is such that the engaging tooth approaches and separates from the facing surface. An elastic member pivotally attached to the operation lever and elastically biasing the engagement tooth member in a direction in which the engagement tooth approaches the facing surface is provided. Since the engaging teeth of the tooth combination member rotate along the facing surface, the structure for engaging and disengaging the engaging teeth and the engaging teeth can be simplified.

The shaft member 50 may be fixed to the plate 30, the shaft member 50 may be formed of a pair of left and right shaft members, or a shaft member that integrally projects from the left and right sides of the movable plate 30. .

As shown in FIGS. 1 to 4, each operating lever 6
At the base end portion of 0, the rack-shaped member 80
On the side of, i.e., on the rear side, a connecting portion 61 that projects a short predetermined length is formed, and the engaging tooth member 7 is formed in the middle part of the connecting portion 61.
The square groove 62 for connecting 0 is formed, and the engaging tooth member 70
Is pivotally attached to the connecting portion 61 by a shaft member 68 so as to be swingable. Each engaging tooth member 70 is formed in a substantially L shape in a plan view by a main body base portion and a protrusion portion that protrudes inward (that is, the rack-shaped member 80 side) from the rear portion of the main body base portion. Engaging teeth 71 that mesh with the engaging teeth 81 of the rack-shaped member 80 are formed, and the upper surfaces of the engaging teeth 71 are partially cylindrical surfaces. Each engaging tooth member 70 is elastically biased toward the rack-shaped member 80 by a leaf spring 75 fixed to the outer surface of the connecting portion 61 with a pair of screws, and the engaging tooth 71 is normally engaged. The state of being engaged with the stop teeth 81 is maintained.

When the operating lever 60 is rotated downward by an arbitrary angle from the state shown in FIG.
The shaft member 50 is driven downward because it is supported by the locking teeth 81 while slightly slipping with respect to 1. Thereafter, when the operation lever 60 is rotated upward by an arbitrary angle, the engaging tooth member 70 swings outward while resisting the elastic force of the leaf spring 75, and the engaging tooth 71 of the engaging tooth member 70 engages. While sliding on the inclined surface of the upper surface of the retaining tooth 81, the engaging tooth 71 engages with the engaging tooth 81 when the operating lever 60 is stopped by moving downward relative to the rack-shaped member 80. . Therefore, the gripping member 68 made of rubber or synthetic resin attached to the connecting lever member 65 is gripped, and the pair of left and right operation levers 60 are vertically swung (rotated) a plurality of times to repeat the shaft member. 50, a pair of left and right connecting members 40, and a movable plate 30.

With, the empty can 5 can be crushed and processed.

When the operating lever 60 swings up and down, the engaging teeth 71 swing up and down along the facing surface of the rack-shaped member 80 on which the locking teeth 81 are formed. The position and the width in the front-rear direction of the rack-shaped member 80 are appropriately set so that the rack-shaped member 80 does not come off. After the crushing process of the empty can 5 is completed, the shaft member 50 and the pair of left and right connecting members 40
In order to return the movable plate 30 and the movable plate 30 to the upper limit position, it is necessary to release the meshing between the engaging teeth 71 and the locking teeth 81. The member 70 is configured to be switchable between the meshing disengagement position shown by the chain line in FIG. 2 and the meshing disengagement position shown by the solid line.

Explaining the detent mechanism,
A vertical hole 63 is formed in the upper half of each connecting portion 61, and a compression spring 64 and a steel ball 66 urged toward the engaging tooth member 70 by the spring 64 are formed in the vertical hole 63. The steel balls 6 are attached to the upper surface of the base of the main body of the engaging tooth member 70 when the engaging tooth member 70 is brought into the meshing position.
The engaging recessed portion 72a into which the steel ball 66 is fitted when the engaging recessed portion 72a into which the 6 is fitted and the engaging tooth member 70 are brought into the disengaged position.
2b are formed. Therefore, when the steel ball 66 is engaged with the engagement recess 72a, the engagement tooth member 70 is held at the meshing position, and when the steel ball 66 is engaged with the engagement recess 72b, the engagement tooth member 70 is engaged. The tooth member 70 is held in the meshing position. The closing plate 67 for supporting the upper end of the spring 64 is fixed to the connecting portion 61 with a screw.

Next, a fall prevention mechanism 90 for preventing the main body frame 10 from tipping forward due to a tipping moment acting on the main body frame 10 when the empty can 5 is pressed will be described. As shown in FIGS. 1 and 2, the fall prevention mechanism 90 includes a pair of left and right metal fall prevention plates 91, and a pair of left and right T grooves 94 for mounting these fall prevention plates 91, respectively.
It consists of and. Each fall prevention plate 91 includes a plate-shaped portion 92 that is trapezoidal in side view, and a T-shaped portion 93 that is integrally formed at the rear end of the plate-shaped portion.

Below each of the reinforcing members 13, there is a T-groove 94 into which the T-shaped portion 93 is fitted and which has the same height as the T-shaped portion 93.
4 is formed in a lower end opening shape. When the T-shaped portion 93 of the fall prevention plate 91 is detachably attached to each T groove 94 from below, the lower end of the fall prevention plate 91 is configured to be flush with the lower end surface of the main body case 11. Since the fall prevention plates 91 project to the front of the main body case 11 to some extent, the pair of left and right fall prevention plates 91 can prevent the main body frame 10 from falling. When the small press 1 is not used, the pair of left and right fall prevention plates 91 can be removed, so that there is no hindrance.

Next, the operation of the above-described manual small press 1 for empty can processing will be described. First, when the empty can 5 is crushed, the movable plate 30 and the like are held at the upper limit position, and the empty can 5 is accommodated in the main body case 11 through the opening 15. Next, while holding the engaging tooth member 70 in the meshing position, the grip member 68 of the connecting bar 65 is grasped and the left and right operation levers 60 are rotated upward by about 45 to 60 with respect to the horizontal plane. From the inclined position, about 45 ~
The receiving plate 20 is rotated by repeating the rotating operation of rotating and driving a plurality of times to the downward inclined position rotated downward by about 60.
With the movable plate 30, the empty can 5 can be strongly crushed and processed. As already mentioned, the left and right operation levers 6
When rotating 0 downward, the engaging teeth 71
Since it is locked by the locking teeth 81 while slipping slightly with respect to 1, a force for strongly driving the shaft member 50 downward acts on both left and right ends of the shaft member 50, and the shaft member 50 is connected to the shaft member 50. The member 40 and the movable plate 30 are strongly driven downward.

Further, as described above, when the left and right operation levers 60 are rotated upward, the engaging teeth 71 swing around the shaft member 68 against the elastic force of the leaf spring 75. Move,
While sliding on the inclined surface of the locking tooth 81, it moves to the position of the locking tooth 81 on the lower side by a plurality of steps, and when the operating lever 60 is stopped, the engaging tooth 71 is locked again by the locking tooth 81. Therefore, it is possible to continuously perform the rotating operation for rotating the left and right operation levers 60 from the upper tilt position to the lower tilt position a plurality of times,
The empty can 5 can be sufficiently pressed (crushed) by a plurality of rotation operations. After the pressing process is completed, the shaft member 50, the connecting member 40, and the movable plate 30 are moved to the upper limit position by moving the grip member 68 upward in a state in which the engagement tooth member 70 is switched to the disengagement position. After the return, the engaging tooth member 70 is switched to the meshing position.

To explain the boosting action, the lever length of the operating lever 60 is L, the effective lever length of the engaging tooth member 70 is d, and the manual driving force for driving the gripping member 68 downward (however, with a foot) Can also be driven) f, shaft member 50
Let F be the downward driving force acting on
F = f × (1 + L / d). That is, the operation lever 6
0, the engaging tooth member 70, and the rack-shaped member 80 constitute a boosting mechanism having a large boosting factor. For example, if the lever length L = 25 cm and the effective lever length d = 2.5 cm,
Power factor (1 + L / d) = (1 + 25 / 2.5) = 11,
And a very large value. In this case, if the manual drive f is, for example, 25 Kg, the pressing force F is 275 Kg,
The empty can 5 can be strongly crushed with a pressing force of 275 kg. Therefore, when processing the empty can 5 made of aluminum with this small manual can 1 for processing empty cans, it is possible to process with very light force, and it is possible to process not only the empty cans 5 made of aluminum but also the empty cans made of steel.

Further, the opposing surface of the rack-shaped member 80 on which the plurality of locking teeth 81 are formed is parallel to the surface orthogonal to the shaft member 50, that is, the surface parallel to the swing surface of the operating lever 60. Since it is formed, since the engaging teeth 71 and the locking teeth 81 can be kept in the meshed state via the leaf spring 75 at all times, the rotating operation of the operation lever 60 is continuously performed a plurality of times during the pressing process, and the empty can 5 Can be pressed efficiently in a short time. The small press 1 is a simple and small press having a small number of parts, and can press an empty can with a small force through the boosting mechanism.

In this small-sized press 1, the empty can 5 is pressed in the vertical direction, that is, in the axial direction.
Can be pressed laterally, that is, in the direction orthogonal to the axis. Particularly, in the case of a large empty can 5 made of aluminum or an empty can made of steel, even if it is pressed by one or more times in the direction orthogonal to the axis. Good. Also, this small press 1
It is needless to say that the can be configured to be used in a horizontal state other than being used in a vertical state.

Here, the main body machine frame 10 may be formed in a rectangular parallelepiped shape, the rack-like member 80 may be integrally formed with a rod-shaped member of the main body machine frame 10, or a rack. The member 80 may be made of a metal plate, and a plurality of locking teeth 81 may be formed on the opposing surface by press molding. Instead of the fall prevention mechanism 90, a fall prevention plate may be fixed to the lower end surface of the main body machine frame 10 so as to protrude to the front of the main body machine frame 10 by a predetermined length.

The rack-shaped member 80 may be fixed to the main body case 11 in front of the guide slit 12. In this case, the rack-shaped member 80 is engaged with the intermediate portion of the operation lever 60 in front of the shaft member 50. A joint member 70 will be attached. Then, since the empty can 5 is pressed when the operation lever 60 is rotated upward, a fall moment that tends to fall backward acts on the main body machine frame 10. Main machine frame 1
It will be attached to the rear side of 0. However, instead of the fall prevention mechanism 90, a fall prevention plate protruding to the front of the main body machine frame 10 by a predetermined length is fixed to the lower end surface of the main body machine frame 10,
The fall prevention plate may be configured to be pressed while being stepped on with a foot. Further, the shaft member 50 may be rotatably connected to the movable plate 30, and the base end portion of the operation lever 60 may be fixedly connected to the shaft member 50. Further, the operation lever 60 needs to be a member having a rigidity sufficient to withstand a manual driving force, and may be made of a pipe material having a rectangular cross section as necessary.

Next, another embodiment in which a part of the above-mentioned embodiment is modified will be described with reference to FIGS. However, only the configuration different from the above embodiment will be described.

Next, as shown in FIGS. 7 and 8, when the operation lever 160 is rotated downward, the engaging tooth 173 is locked by the locking tooth 181 and the engaging tooth 173 cannot move upward. Therefore, the shaft member 150 and the movable plate 130 are pressed and driven downward through the movement of the pivot shaft 175 to the rack-shaped member 180 side, and the empty can is placed between the movable plate 130 and the receiving plate. It is crushed by the moving amount of the member 150, and the state shown in FIG. 8 is obtained.

Thereafter, when the operating lever 160 is rotated upward by an arbitrary angle, the engaging tooth member 170 rotates counterclockwise while resisting the biasing force of the torsion spring 171, and the engaging tooth member 170 moves. When the engaging teeth 173 move downward relative to the rack-shaped member 180 while sliding on the inclined surface on the upper surface of the locking teeth 181, and the operation lever 160 stops as shown in FIG. The engaging teeth 181 mesh with the joint teeth 173. Therefore, by repeatedly swinging (rotating) the operation lever 160 up and down a plurality of times continuously, the shaft member 150 and the movable plate 130 are pressed downward to drive the receiving plate and the movable plate 130. With, empty cans can be pressed.

After the crushing process of the empty can is completed, the shaft member 1
When returning 50 and the movable plate 130 to the upper limit position,
When the operating toothed member 170 is operated to switch the engaging tooth member 170 to the retracted position, the steel ball 168 of the detent mechanism engages with the locking recess 176, so that the engaging tooth member 170 is held at the retracted position. In this state, the operation lever 160 is moved upward to return the shaft member 150, the movable plate 130, and the engaging tooth member 170 to the upper limit position. This small press 1
In No. 01, the empty can can be efficiently pressed in a short time by continuously rotating the operation lever 160 a plurality of times during the pressing as in the above-described embodiment. Further, the small press 101 is a simple, small and lightweight press having a small number of parts, and can press an empty can with a small force through a boosting mechanism having a principle similar to that of the above embodiment.

The small presses 1, 101 may be incorporated in an automatic vending machine. In this case, the main body machine frame may be configured integrally with the machine frame of the vending machine, or the main body machine frame may be fixedly configured to the machine frame of the vending machine. It should be noted that the above-described embodiment and other embodiments are merely examples, and various modifications are added to the engaging tooth member, the engaging tooth, the rack-shaped member, and the like without departing from the spirit of the present invention. Of course, it can be implemented.
